1. Faults caused by improper selection of electrical appliances in the Outdoor Fiberglass Box distribution box: Due to the inappropriate selection of the capacity of the AC contactor during the manufacturing process, the AC contactor of the same capacity is installed in different socket circuits, and the unbalance of the three-phase load is not considered . However, it is impossible to increase the current level selection based on the normal selection model based on the partial outlet contact current level.
2. Ambient temperature impact caused by low-voltage electrical appliances: The low-voltage electrical appliances in the distribution box are composed of fuses, AC contactors, residual current-operated protectors, capacitors and meters. The upper limit of the ambient air temperature does not exceed 40°C; the average value of the 24-hour ambient air temperature does not exceed 35°C; the lower limit of the ambient air temperature is not less than-5°C or -25°C. Therefore, in the hot summer, the temperature inside the box will reach 60°C or higher, and the temperature at this time greatly exceeds the ambient temperature specified by these appliances. When the height of the distribution box in Shandong is less than 500 mm, it shall not exceed 1.5 mm. When the height of the distribution box in Shandong is greater than 500 mm, it shall not exceed 3 mm. The pipeline should be straight and the exposed length should be less than 5 mm. .
